(2) gearratio determines
Gearratio refers to the ratio of servomotor rotating speed and yarn roller rotating speed.Will adhere to following principle when choosing draft gear and determine gearratio: (1): gearratio, generally greater than 15, guarantees enough carry-over moments.(2): the dried greatly 100r/min of the speed of servomotor while spinning basic yarn.(3): the maximum speed of servomotor, namely spin the speed of ring less than 1700r/min.(4): gearratio is slightly larger than drafting multiple, but can not be too large.
(3) twist determines
Under normal circumstances, stocking yarn is distributed cotton better, because the common grasp less than normal of the twist, but namely to have ring to have again spandex core-covered due to this yarn, so its twist should 20% left and right bigger than normal, general twist factor is controlled at 380～430 left and right
(4) the nip gauge piece determines
For preventing not opening because of the excessive drawing-off of drafting force, cause out hardhead or large burr, should be than the large shelves of normal yarn.
(5) selection of steel traveler
Because the parameter of slub yarn changes greatly, basic yarn number number differs greatly with thick section number number, for the fluctuation that reduces the balloon tension size and make ring partly by smooth and easy, usually selects passage spaciousness, underslung steel traveler, and the steel traveler cross sectional shape is advisable so that height is arc.Steel traveler weight is selected between basic yarn number number and average number.
(6) the joint shape parameter determines
The joint shape parameter is to regulate on the ring two ends to rise and the decline curve shape, and it can change the style of the shape of ring.Numerical value is less, and basic yarn is crossed and getted over smoothly to ring, otherwise steeper.Transitions smooth is conducive to twist with the fingers to the ring transmission, forms brute force high, is conducive to weave.
(7) spandex unit
The silk that uses because of us is the Dupont silk, and Inner is in reliable in quality, and silk will be put the 24 hours balance humitures in workshop before using, and prevents a bifurcated, and other godet roller occurs the situations such as fracture of wire, and godet roller will go slick, and prevents that misdraft from occurring.Technique is in Table 4:
